INTRODUCTION AND OBJECTIVES: Although standard surgical treatment of a testicular tumour is orchiectomy, use can be made of testis-sparing surgery in selected cases, based on tumour markers, tumour size, and histopathological findings. Our objective is to become acquainted with the indications of testis-sparing surgery as a treatment for the incidental finding of a palpable and non-palpable testicular mass. MATERIAL AND METHODS: A retrospective study was conducted on 22 patients younger than 18 years diagnosed with a testicular tumour between 2000 and 2014...

The Achilles tendon has a unique structure-function relationship thanks to its innate hierarchical architecture in combination with the rotational anatomy of the sub-tendons from the triceps surae muscles. Previous research has provided valuable insight in global Achilles tendon mechanics, but limitations with the technique used remain. Furthermore, given the global approach evaluating muscle-tendon junction to insertion, regional differences in tendon mechanical properties might be overlooked. However, recent advancements in the field of ultrasound imaging in combination with speckle tracking have made an intratendinous evaluation possible...

We present the case of a 59-year-old female who developed rheumatoid arthritis in 2007. Right total knee arthroplasty (TKA) was performed in 2008. Although she was treated with methotrexate (MTX) after the operation, this treatment was insufficient. Infliximab (IFX) was introduced in 2001, and she achieved clinical remission. Left TKA was performed in October 2014. Because active synovitis was not detected by ultrasound after the operation, IFX was discontinued. She had been treated with MTX 8 mg weekly. However, arthralgia of the bilateral knees developed in March 2015...

Depending on the type and acuteness, diseases of the aorta can be imaged by a variety of techniques. Modalities and quality of imaging have developed rapidly in recent years. In combination with the clinical assessment of patients, the results obtained by imaging determine the further management. They not only establish the underlying diagnosis but provide the information essential for indications, planning and reassessment of therapy, as well as for evaluation of the clinical course and surveillance. Whereas conventional catheter-guided angiography and intravascular ultrasound are only used in exceptional cases and then in conjunction with interventional therapy, cross-sectional imaging modalities, such as contrast-enhanced computed tomography (CT) angiography and magnetic resonance imaging (MRI) are nowadays the mainstay of diagnostics...

High-intensity focused ultrasound (HIFU) is widely applied to tumors in clinical practice due to its minimally invasive approach. However, several issues lower therapeutic efficiency in some cases. Many synergists such as microbubbles and perfluorocarbon nanoparticles have recently been used to improve HIFU treatment efficiency, but none were determined to be effective and safe in vivo. In this study, nanoscale bubble-generating liposomes (liposomes containing ammonium bicarbonate [Lip-ABC]) were prepared by film hydration followed by sequential extrusion...

Patient histories that include wrist pain can be pivotal in the distinction between intersection syndrome (IS) and the more common de Quervain's tenosynovitis (DQT). Presented here is a 26-year-old pregnant woman with a history of rowing who developed left radial/dorsal wrist pain and a rubbing/squeaking sensation. Nine months of conservative DQT therapy and a landmark-guided corticosteroid injection failed to relieve her symptoms. An in-clinic ultrasound showed tenosynovitis at the intersection of the first and second compartments, confirming a diagnosis of IS...

Endoscopic retrograde cholangiopancreatography (ERCP) is a key endoscopy skill used to diagnose and treat pancreatobiliary diseases. However, its diagnostic use is decreasing in favor of other less invasive methods such as magnetic resonance cholangiopancreatography and endoscopic ultrasound. Alternatively, its use has become more important in the therapeutic area. ERCP trainees must know the anatomy and physiology of the pancreatobiliary system, several key basic skills, and complications of a successful procedure...

Endoscopic ultrasound (EUS) has become an essential tool for the diagnostic and therapeutic intervention of gastrointestinal diseases. Beyond the drainage of fluid collections, it enables decompression of inaccessible bile and pancreatic ducts, the gallbladder, and the creation of anastomosis within the gastrointestinal tract using fully lumen-apposing stents. This review explored the safety and efficacy of these novel procedures and discussed the training pathway that is necessary to perform them efficiently and safely...

The sub-micron phase change contrast agent (PCCA) composed of a perfluorocarbon liquid core can be activated into gaseous state and form stable echogenic microbubbles for contrast-enhanced ultrasound imaging. It has shown great promises in imaging microvasculature, tumour microenvironment, and cancer cells. Although PCCAs have been extensively studied for different diagnostic and therapeutic applications, the effect of biologically geometrical confinement on the acoustic vaporisation of PCCAs is still not clear...

Severe toxicity and poor tumour penetration are two intrinsic limited factors to hinder the broad clinical application for most of first-line chemotherapeutics. In this study, a novel vitamin E succinate-grafted ε-polylysine (VES-g-PLL) polymer was synthesized by using ε-polylysine as backbone. By adjusting VES graft ratio, VES-g-PLL (50) with a theoretic VES graft ratio of 50% could self-assemble into a supermolecular micelle with a hydrodynamic diameter (Dh) of ca.20nm, and Zeta potential of 19.6mV. VES-g-PLL micelles themselves displayed a strong anti-tumour effect on glioma...

Efficient intracellular delivery of biologically active macromolecules has been a challenging but important process for manipulating live cells for research and therapeutic purposes. There have been limited transfection techniques that can deliver multiple types of active molecules simultaneously into single-cells as well as different types of molecules into physically connected individual neighboring cells separately with high precision and low cytotoxicity. Here, a high frequency ultrasound-based remote intracellular delivery technique capable of delivery of multiple DNA plasmids, messenger RNAs, and recombinant proteins is developed to allow high spatiotemporal visualization and analysis of gene and protein expressions as well as single-cell gene editing using clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein-9 nuclease (Cas9), a method called acoustic-transfection...
